The design of meshing gears is complex especially if an optimum solution is required in an application. British, American and ISO standards describe analytical techniques in much detail but they tend to be rather daunting to the inexperienced and infrequent gear designer.

Frequently a simplified analytical selection procedure is given but for a more comprehensive explanation it is necessary to make reference to the appropriate standard for details.
The following list give some additional notes:-
